* lwip: Allocate the loopback netif by defaultJoan Lledó2023-12-021-7/+7
| | | | | | | | | | | | | | | | | | | | | The translator received a null `netif_list` during initialization, this caused a few bugs. When started without parameters, the translator didn't add any new interface to `netif_list`, and that broke any subsequent fsysopts over the translator, as the stack was being initialized again instead of being reconfigured. DHCP was broken because the translator is usually installed without parameters, which are supposed to be added by the DHCP client through fsysopts. The absence of an allocated `netif_list` also prevented configuring a loopback interface. After these changes, starting the translator always allocates one interface and configures it as loopback.

* Modernize code by removing use of old style definitions.Flavio Cruz2023-04-031-2/+2
| | | | | Also add -Werror=old-style-definition to enforce new code. Message-Id: <ZBZ+8xf7GHy2RT/h@jupiter.tail36e24.ts.net>
* lwip: Fix bug: Error handling on configure_device()Joan Lledó2019-05-111-5/+3
| | | | | | | * lwip/lwip-util.c: * EINVAL was never being returned. * Return error code for tcpip_callback() as errno. Message-Id: <20190511093202.9763-2-jlledom@member.fsf.org>
* lwip: Error handling when calling update_if()Joan Lledó2019-05-021-29/+33
| | | | | | | * lwip/lwip-util.c: * Check for errors when calling update_if() inside a thread-safe context. Message-Id: <20190502095502.10926-4-jlledom@member.fsf.org>
* lwip: Stop using netifapi.Joan Lledó2019-03-311-28/+45
| | | | | | | | | | | | | | Use tcpip_callback() to reconfigure interfaces in a thread-safe context instead. * lwip/lwip-util.c: * Replace all netifapi calls by their non-netifapi versions. * update_ifs() is called through tcpip_callback(). * lwip/options.c: * Call init_fs() through tcpip_callback(). * lwip/port/netif/ifcommon.c: * Replace all netifapi calls by their non-netifapi versions.
